I don't think that the problem is related to anything on VDR

AFAIK the bandwidth from ARM to PCI bus is very limited on
full-featured cards. With 3 recordings being transfered to VDR
there is simply not enough bandwidth left for the OSD transfers.
Hence the LoadBitmap timeout.

I experience the problem since VDR introduced concurrent
recordings and I cannot believe that there is any VDR / firmware
combination which doesn't show this behaviour as it's IMO a
hardware limitation.

Budget cards doesn't have this limitation, they can transfer the
full transponder without problems.
